Description

TECHNICAL FIELD [0001] The present invention relates to an induction unit for an underground structure, a module unit, and a method of constructing an underground structure using the same.

The present invention relates to an induction unit for an underground structure, a module unit, and a method of constructing an underground structure using the same. More specifically, in the construction in which the pressurized propulsion pipe is press-fitted into the underground structure, it is difficult to adjust the position that occurs when pushing in the conventional multi-type press-in type propulsion tube, the inconsistency of the connection portion between the adjacent multi- The present invention relates to an induction unit for an underground structure, a module unit and a method of constructing an underground structure using the same.

Generally, there is a method of constructing an underground structure by a method of constructing a structure in the ground, and a method of constructing an underground structure by opening and closing.

If it is necessary to install underground roads, tunnel structures, etc. by crossing existing roads and railways, it is not possible to move due to construction problems, In the underground structure construction method by non-installation, forward bases and reaching bases of the operation concept are indispensable for both sides of roads or obstacles crossing. Typical non-installation type underground structures construction methods include armor traction method and steel pipe loop method .

Since the present invention can be applied mainly to the non-installation type steel pipe loop construction method, an example of a conventional steel pipe loop construction method will be described.

That is, among the conventional steel pipe loop methods, the PRS method is a method in which the single-pipe type impulse propulsion pipes are pushed adjacent to each other, the side connecting portions are further reinforced by the bundle reinforcing bars, and the transverse rigidity is secured Thereby making it possible to construct a steel pipe loop structure without a separate transverse support beam.

That is, the PRS method is a method in which a pressurized propulsion pipe (steel pipe) is press-fitted in succession in accordance with the outline of a structure to be installed after a work area (forward base and reaching base) is installed on both roads or trails to be traversed, It can be said that the pipe (steel pipe) is press-fitted one by one.

In addition, a parallel type propulsion steel pipe assembly and a method of constructing an underground structure using the same are introduced by other conventional non-installation type steel pipe loop construction method (Patent No. 0995384). This is a technique commonly used in STS construction method, (Parallel steel pipe) in which two or three steel pipes are connected to each other, and then a reinforcing bar having a fixing plate is installed on the transverse connection portion of the press-fitting propulsion pipe without side cutting, and concrete is laid It is to construct an underground structure.

In the conventional non-attaching steel pipe looping methods (PRS method, STS method), the work is performed by press-fitting at the back of the press-fitting propulsion tube and excavating the soil-to-be-ground at the tip of the press- The advantage is that the shape of the indentation propulsion tube is not limited.

However, mechanical excavation apparatuses corresponding to various sectional shapes have not been commercialized at present, and it is not easy to excavate the inside of the press-fit propelling tube by the human force, so that the non-affixing steel pipe loop method of pushing the press- There is a limitation that can not be overcome.

1 shows a prior art press-fitting device for a conventional steel pipe loop structure. A guide portion 12 formed to be concave on the front end of the main body; a connection portion 13 formed on the rear of the main body so as to be inserted into and connected to the inside of the steel pipe; (20), and an actuator (30), as shown in FIG.

That is, it can be seen that the end press-fitting device by the press-fitting propulsion pipe (1) and the propulsion support pipe (10) is a method of fitting the propulsion support pipe after the end portion is excavated by using the press- have.

In this case, in the construction of the indentation propulsion tube, it is possible to secure a certain degree of workability by the end press-fitting device. However, the end press-fitting device of such a steel pipe loop structure has a problem in that the push- And the efficiency of the pipe is inferior due to the construction of a single pipe type construction in which an indentation propulsion pipe is constructed one by one.

Further, in the case of the conventional parallel type press-in type propulsion tube (bundle tube type), since a plurality of press-in propulsion tubes are integrally press-impregnated, there is an effect of constructability and air shortening in comparison with press- Since the indentation load is 2-3 times larger than that of the single pipe in the single pipe type or bundle pipe type, there is a great possibility that derailment of the indentation propulsion pipe due to breakage of the guide on the side of the propulsion tube is increased , There are many working points of the joint connection part, so there is a problem that leakage occurs in many joint parts when rainwater or groundwater flows in the upper part of the road.

Also, in the prior art, the bundle steel pipe itself is used merely as a formwork. In addition, since a separate propulsion pipe side portion must be cut or a reinforcing bar installation work must be performed while moving within a narrow indentation propulsion tube, work is troublesome and an enormous construction cost is added There is a problem that it is inevitable.

For example, in the case of a small scale of an underground structure, a module unit for an underground structure in the form of a bundle tube manufactured as it is in a cross-sectional shape is manufactured and press-fitted into the underground structure. If the underground structure is large, The module unit for the underground structure is press-fitted into the ground so that the press-in resistance can be minimized to enable precise construction, thereby preventing damage to the connection portion of the module unit for the underground structure, thereby providing a more efficient and easy- And to provide a method of constructing an underground structure using the same.

In order to achieve the above object,

First, the module unit for the underground structure is made in the form of a bundle tube. The module unit for the underground structure includes a propulsion tube spaced apart in parallel from each other and a double junction plate and an internal vertical plate extending horizontally between the propulsion tubes.

The module unit for the underground structure is press-fitted into the ground to form a loop or a wall of the underground structure, and then the connection portions of the module units for each underground structure are welded in a zigzag manner instead of the straight welding, Therefore, the cutting type of the propeller side portion for installing a reinforcing member such as a conventional horizontal reinforcing bar becomes unnecessary.

Secondly, in case of constructing a small-scale underground structure, the module unit for an underground structure may be manufactured by forming and inserting a module unit for the underground structure in the size and shape of the cross-section, and if a large-scale underground structure is to be constructed, So that they are press-fitted while being connected to each other.

Thirdly, according to the present invention, the module unit for an underground structure should be press-fitted into the ground. If the under-press resistance is increased, the module unit for the underground structure is not pressed in a desired direction due to a left- So that the workability is deteriorated due to the twisting of the connecting portion of the module unit for the underground structure.

In order to solve this problem, the present invention firstly guides the induction unit for the underground structure to the reaching base from the forward base so that the module unit for the underground structure can be guided to the ground. That is, the induction unit for the underground structure can be installed before the module unit for the underground structure is installed, and the induction unit for the underground structure can be easily press-fitted into the ground in the form of a guide tube spaced in the desired direction. Therefore, The module unit for the underground structure is connected at the forward base, and each unit is integrally press-fitted forward.

That is to say, the above-mentioned underground structure induction unit serves as a front wedge of the module unit for underground structure, thereby reducing the press-in resistance while ensuring the directionality, and pushing the module unit for underground structure integrally forward.

Since the module unit for an underground structure is basically used in the form of a propelling tube, the present invention can rapidly construct an underground structure by accelerating a pushing-in speed in comparison with a single-pipe type.

In addition, the module unit for an underground structure has a large in-ground resistance at the time of press-in. However, in order to reduce the in-ground resistance, it is possible to precisely construct the module unit using the induction unit for the underground structure. It is possible to connect the module unit for the underground structure with ease because no deformation or warping occurs.

In addition, the connection part of the module unit for the underground structure which is driven by the slab and the wall, that is, the connection part where the connection plate is inserted into the fitting rib of the module unit for the underground structure is formed by one side of the fitting rib having the staggered shape and the connecting plate by zigzag Welding. Therefore, it is possible to prevent the damage of the connection portion due to the stress concentration phenomenon occurring in the conventional linear welding, and to provide a safe and reliable bonding structure against various stresses, so that it is suitable for connection of structures subjected to large loads such as underground structures .

Further, the underground structure using the module unit for an underground structure of the present invention is filled with concrete, and then the underground concrete is laid for the construction of the underground structure. Therefore, not only the side portions of the conventional press-in grooves but also the lateral connection reinforcing bars are omitted, and the module units for the underground structure are directly welded to each other (steel) to construct the module units for the underground structure. It is possible to design and construct an efficient underground structure which is very economical and waterproof.

≪ Induction unit 200 for underground structure of the present invention and module unit 100 for underground structure >

FIG. 2A is a construction view of an induction unit 200 for an underground structure and a module unit 100 for an underground structure according to the present invention, FIG. 2B is an illustration of a module unit 100 for an underground structure, Fig. 10 is a view illustrating welding of the concave / convex shape of the fitting rib 310 of the unit 100 and the connecting plate 320;

2A, the induction unit for underground structure 200 is shown as a round steel pipe as induction pipes 110 which are press-fitted into a ground G in the shape of a single pipe. However, a rectangular steel pipe may be used.

That is, they are separated from each other according to the cross-sectional shape of the underground structure first in the ground in the form of a single pipe, and are press-fitted into the ground at the forward base, and these guide pipes (110)

At this time, the module unit 100 for the underground structure is connected to the rear of the induction unit 200 for the underground structure at the forward base.

Such a module unit 100 for an underground structure is a steel pipe which is press-fitted into a bundle tube,

Four propelling pipes 110 are spaced apart from each other and a double junction plate 120 is integrally formed between the propelling pipes 110.

Although the propelling tube 110 is shown as a circular steel pipe, a square steel pipe may also be used, and the number of the installation can be changed according to the distance between the induction units 200 for underground structure.

The double junction plate 120 is formed of an upper joining plate 121 and a lower joining plate 122 in the form of a horizontal plate and the extension of the joining plate 120 is adjusted according to the state of the stratum and the toe, The inner vertical plate 130 may be included and the inner vertical plate 130 may be omitted for securing rigidity as shown in FIG. 2B.

The upper and lower ends of the upper joint plate 121 and the lower joint plate 122 are connected to both inner side surfaces of the propelling tube 110. The upper and lower ends of the inner vertical plate 130 are connected to the upper joint plate 121, And it is connected to the upper surface of the plate 122 in a generally central bottom.

Therefore, when the propulsion tube 110 spaced apart from each other is press-fitted into the ground, the required rigidity can be sufficiently secured by the double joint plate 120, and the twist due to the internal vertical plate 130 can be effectively coped with.

After the concrete is filled in the module unit 100 for the underground structure, the upper and lower joint plates 121 and the inner bottom plate 130 of the lower joint plate 122 are subjected to the bending tensile material, Shear stiffeners, and the like.

The module unit 100 for an underground structure includes a module unit 100a for an upper underground structure formed of a roof structure A1 of an underground structure as shown in FIG. 2A and a module unit 100a for a sub- (100b) are formed integrally with each other.

First, when the in-ground structure induction unit 200 is first press-fitted to the arrival base and the module units 100 for the underground structure are connected to each other at the trailing end, the induction unit 200 for the underground structure is moved in the press- Wedge, and guide pipe. Therefore, when the module unit 100 for the underground structure is pushed in at the rear, the pushing and pushing operation becomes very easy.

At this time, the pressurization of the guide unit 200 for the preceding underground structure is carried out as precisely as possible with the greatest precision, and then the guide unit 200 for pressurized injection is smoothly extracted from the reaching base, It is preferable that the outer periphery of the induction unit 200 is formed while being injected with a scraper such as bentonite.

It is possible to push and push the module unit 100 for the underground structure more easily and precisely than when the module unit for the underground structure is pulled forward by using the steel wire W from the reaching base.

In addition, it is preferable to apply a bentonite liquid or the like while injecting into the surrounding ground of the module unit 100 for the underground structure so as to facilitate press-fitting.

In other words, since the underground structure induction unit 200 serves as a wedge and a guide pipe, the precise indentation propulsion of the module unit 100 for the underground structure is induced. In addition, if necessary, the inserting method using the steel wire (W) Can be supplemented.

Further, according to FIG. 2B, it can be understood that the cross section of the propulsion pipe 110 of the module unit 100 for an underground structure can be formed as a propulsion pipe, which is a round steel pipe, or a propulsion pipe, which is a square cross section. Accordingly, the induction pipes 210 of the induction unit 200 for the underground structure are formed to have circular or square cross-sections corresponding to each other, and the same diameters or diameters are used.

At this time, the module unit 100 for an underground structure can be manufactured as a single structure as shown in FIG. 2A, but it can be divided into two as shown in FIG. 2B.

That is, in the case of the module unit 100a for the upper underground structure corresponding to the roof structure A1 of the underground structure as shown in FIG. 2C, the two walls A2 and the connecting plate 320 of the module unit 100b for underground structure, It is seen that the fitting rib 310 is extended downward from the uppermost end propelling tube so as to be fitted and connected to the upper end propelling tube.

Further, in the case of the module unit 100b for the in-ground structure in the case of the wall structure A2 corresponding to the wall A2 of the underground structure, it is possible to connect the upper wall of the underground structure A2 to the inner wall of the module unit 100a for the underground structure It can be seen that the connecting plate 320 is extended upward.

In addition, the fitting rib 310 and the connecting plate 320 are basically inserted and connected to each other, but they are bent together. That is, the fitting ribs 310 and the connecting plate 320 are welded to each other to ensure structural integrity with each other to function as a structure.

Although such welding is generally performed by linearly welding the connection rib 310 and the connection plate 320, the present invention follows a welding method for securing structural integrity.

As shown in FIG. 2C, the upper or lower ribs of the fitting rib 310 are formed into a concave-convex shape in the longitudinal direction.

The insertion rib 310 of the side press-fitting driving tube is formed such that one rib 131 and the other rib 132 are spaced apart from each other and one rib 131 is formed as a concave and a convex rib.

The connecting plate 320 in the form of a plate sandwiched by the fitting ribs 310 is formed in a concavo-convex shape with one rib so as to prevent damage to the welded joint due to the stress concentration phenomenon in the conventional linear welding It is possible to effectively disperse and cope with stresses acting in various directions.

As a result, the module unit 100a for the upper underground structure and the module unit 100b for the underground structure A2 in the underground structure can be seen that the fitting ribs 310 and the connecting plate 320 are bent together And it has an important effect of functioning as a structural member acting as an integral part.

At this time, the module unit 100a for the upper underground structure is firstly pressed, and the module unit 100b for the underground structure is inserted into the module unit 100a for the upper underground structure by using the connecting ribs 310 and 320 So as to be crimped to each other.

≪ Coupling of the rear part of the induction unit 200 for the underground structure of the present invention and the module unit 100 for the underground structure >

3 shows a connection diagram of an induction unit 200 for an underground structure and a module unit 100 for an underground structure according to the present invention.

As described above, the induction unit 200 for an underground structure of the present invention is first press-fitted at the time of construction, and then the module unit 100 for an underground structure is bound to the rear of the induction unit 200 for underground structure, The induction unit 200 and the module unit 100 for the underground structure are integrally press-fitted together at the rear end.

The connecting pipe 210 of the induction unit 200 for the underground structure and the propulsion pipe 110 of the module unit 100 for the underground structure are connected to each other using the overlocking plate 220 and the connecting bolt 230 do.

Since the induction pipe 210 and the propulsion pipe 110 are formed of a circular steel pipe or a square steel pipe, the welding line may be formed as a circular or square line when welded to each other.

The present invention is characterized in that an over-dam reinforcing plate 220 is integrally formed on an inner surface of a rear end of an induction pipe 210 at a forward end so as to cover an inner connecting portion between a induction pipe and a propulsion pipe, And they are simply connected to each other by the bolts 230 using the bolt holes.

The underground structural body induction unit 200 exposes the overburden reinforcing plate 220 at the forward base and the module unit 100 for the underground structure is connected to the overburden reinforcing plate 220 and the connecting bolts 230 The module unit 100 for the underground structure and the module unit 100 for the underground structure are integrally press-fitted together at the rear end.

≪ Method of constructing underground structure using induction unit 200 for underground structure and module unit 100 >

FIGS. 4, 5, and 6 show a method of constructing an underground structure using the induction unit 200 for an underground structure and the module unit 100 according to the first, second, and third embodiments of the present invention.

In the first embodiment, when the in-ground structure induction unit 200 is a small-sized underground structure, the under-ground structure is manufactured in the form of indentation propulsion, while the second and third examples are large- The in-ground structure induction unit 200 is divided into, for example, a loop structure A1 and a wall structure A2.

[Method of constructing underground structure using induction unit 200 for underground structure and module unit 100 according to Embodiment 1]

In the first embodiment, when the in-ground structure induction unit 200 is a small-sized underground structure,

First, the underground structure induction unit 200 is preliminarily inserted into the ground from the forward base to the arrival base. At this time, the induction pipes 210 of the induction unit 200 for the underground structure are press-fitted four times corresponding to the cross-sectional shape of the underground structure.

Next, the module unit 100 for an underground structure integrally formed at the rear of the induction pipes 210 of the induction unit 200 for the underground structure is connected to each other as shown in FIG.

Next, the module unit 100 for the underground structure is press-fitted at the rear end, and the underground structure induction unit 200 is pushed to the arrival base while connecting the module units 100 for the underground structure from the forward base to the arrival base And press.

The induction unit 200 for the underground structure is gradually extracted at the construction end point and the induction unit 200 for the underground structure is separated from the module unit 100 for the underground structure and is recovered. Since the module unit 100 for an underground structure and the induction unit 200 for an underground structure are connected to each other by a connection bolt and a damper, simple separation operation is possible.

Accordingly, the induction unit 200 for the underground structure is partly disassembled and recovered while the module unit 100 for the underground structure pushes in and out from the forward base to the arrival base.

Although the partial dismantling is not shown, the connecting pipe 210 connected to the module unit for the final ground structure 100 and the connecting unit for the underground structure induction unit 200 is finally dismantled .

The module unit 100 for the underground structure is filled with the concrete C so that the module unit 100 for the underground structure is connected to the loop structure A1 of the underground structure A, (A2) as a structural member. At this time, the inside of the underground structure is excavated, and a bottom plate is formed by using concrete between the lower inside to secure the space inside the underground structure.

At this time, the upper joining plate 121 and the lower joining plate 122 internal vertical plate 130, which constitute the module unit 100 for an underground structure, act as inner reinforcing bars themselves, Not only can the construction cost be reduced, but also the ease of construction and workability can be ensured.

According to this method, since the module unit 100 for an underground structure does not generate a connection site, there is no fear of leakage due to an excellent or underground water penetrating from the upper part of the road, and the construction of the underground structure can be completed more quickly.

[Method of constructing an underground structure using the induction unit 200 for an underground structure and the module unit 100 according to the second and third embodiments]

In the second embodiment, when the underground structure is large, the module unit 200 for the underground structure is divided into the loop structure A1 and the wall A2, for example. In the second embodiment, 3 is a square pipe type.

First, the induction unit 200 for the underground structure is preliminarily inserted into the earth from the forward base to the arrival base. At this time, the induction pipes 210 of the induction unit 200 for the underground structure are press-fitted eight times corresponding to the cross-sectional shape of the underground structure.

Four induction tubes 210a corresponding to the loop structure A1 of the underground structure and four induction tubes 210b corresponding to the two walls are respectively pressed first. Here, it is also possible to press-in the induction unit for the underground structure at the slab portion of the underground structure and the wall portion of the underground structure to install the module unit for the upper underground structure, and then press the both induction pipes 210b.

Next, the module unit 100a for the underground structure is integrally connected to the rear of the induction pipes 210 of the induction unit 200 for the underground structure as shown in FIG.

That is, the module unit 100a for the upper underground structure corresponding to the roof structure A1 of the underground structure is first connected to the induction pipe 210a, and the module unit 100a for the upper underground structure is repeatedly inserted ).

At this time, as the module unit 100a for the upper underground structure is press-fitted, four guide pipes 210a installed at the upper portion are extracted from the arrival base and recovered.

After the module unit 100a for the upper underground structure is press-fitted, the module units 100b for both side underground structures are press-fitted.

The connection plates 320 of the module units 100b for both side protection structures are fitted to the fitting ribs 310 formed in the module unit 100a for the upper underground structure, The module unit 100b for the ground structure is connected to the induction unit 200 for the underground structure while pushing the induction unit 200 to the reaching base.

Accordingly, the induction unit 200 for the underground structure is recovered while partially dismantling the submerged structures in the reaching base in the process of pushing in the module units 100a and 100b for the upper and lower side underground structures.

 After the press-fitting is completed, the fitting ribs and connecting plates of the module units 100b for both side in-ground structures are stitched together by the zigzag welding so that the ribs and the connecting plates are bent together to form a module The unit 100b is integrated with the module unit 100a for the upper underground structure.

The module unit 100 for the underground structure is connected to the loop structure of the underground structure A by filling the concrete C in the module units 100a and 100b for the upper and the lower in- A1 and the two-walled structure A2 as an underground structure supporting the upper load.

 The upper joint plate 121 and the lower joint plate 122 internal vertical plate 130 constituting the module unit 100 for an underground structure respectively serve as structural members such as a flexural tensile member, a flexural compressive member and a shear reinforcement member The inner vertical plate 130 serves as an inner reinforcing member of the induction unit 200 for the underground structure. In addition, since the side is cut in the steel pipe and a separate transverse reinforcing bar is not installed, the construction cost is reduced, So that it is possible to secure a simple workability and workability.
